Dimethyl Diphenyl Ether
Dimethyl diphenyl ether (bis(2,6-dimethylphenyl) ether) is a specifically enumerated aromatic diether compound featuring two methoxy-substituted phenyl rings. It qualifies for HTS 2909.30.0500 as one of the three named products in this chemical-specific subheading. Commonly used as a heat transfer fluid and chemical intermediate.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for other alkyl diphenyl ethers
Only dimethyl diphenyl ether is specifically named; analogous structures fall into the general aromatic ethers provision.
If imported as anti-freeze or heat transfer fluid preparation
Formulations for specific end-uses like heat transfer become Chapter 38 preparations, not pure Chapter 29 compounds.
If predominantly hydrocarbon-like with minimal oxygen
Highly alkylated ethers may be assessed for classification in petroleum oils if ether function is incidental.

Import Tips & Compliance
• Include flash point and boiling point data in documentation to distinguish from general diphenyl oxide mixtures
• Verify 99%+ purity to avoid reclassification as mixtures under Chapter 38 if impurities exceed 1%
• Obtain end-use statements if imported for high-temperature applications to preempt industrial chemical reviews
